Today I'm driving to the tuning service, they will do the roof waterproofing. I'll let you know what happened.

The front roof seal has deteriorated .
In the photo, the number is -8.
It is necessary to change the seal , but it is not available at a dealer not in the USA , not in Dubai , not in China .

My second row passenger side leaks. Two TSB’s later and it still leaks..albeit in a different location now…

I got my Hummer cheap because it was sent back as “defective” to GM and branded a lemon because of… you guessed it, the roof panels leaking. It doesn’t leak inside tho, but the panels have water runoff directly to the front windows. Its a design flaw, hopefully you can get it resealed properly.

Hi, the roof was sealed in front, but they said we don't know how long it would last, but when I came to pick up the Hummer, it was raining heavily, I opened the back door and saw that the roof was also leaking in the back, I don't know what to do anymore!

I’ve noticed the same issue, and it’s hard to believe it slipped past engineering during development. See my thread here:

Did GMC test the Hummer EV in the rain?

I drove the Hummer in heavy rain for the first time yesterday. Driving it was great! The triple windshield wipers work very well. However, I got soaked getting in and out of the Hummer! There are no gutters on the skyroof panels, so the water just dumps right into the vehicle. This...

Too bad there isn't an aftermarket solution for this.

Still, between the triple wipers and the windshield layout, the Hummer’s visibility in heavy rain is by far the best of any vehicle I’ve owned.
